The chemical challenge in the industrial environment
In many industrial processes, aggressive chemical agents such as hydrochloric acid (HCl), sulphuric acid (H₂SO₄), hypochlorite, hydrofluoric acid (HF) or even substances such as hydrogen peroxide (H₂O₂) have a high degradation potential on traditional metal components.
These substances, present in industries such as chemistry, microelectronics, water treatment, pharmaceuticals, food or wafer etching and cleaning processes, attack metal surfaces, causing:
- Accelerated corrosion
- Loss of torque
- Chemical or mechanical leaks
- Contamination of critical processes
Standard screws, even in stainless steel, often does not provide the strength needed for these environments.
